General description

A cell-permeable thiobarbituryl-benzoate compound that acts as a highly potent and reversible inhibitor of lymphoid tyrosine phosphatase (LYP) (IC50 = 508 nM) and thereby enhances TCR signaling in intact cells. Exhibits competitive to mixed mode of inhibition (Ki = 384 nM). Also shown to inhibit the mutant, disease associated LYP-Trp620 activity. Binds to the phosphate-binding loop and mimicks the phosphotyrosine moiety of substrates. Displays acceptable selectivity over a wide range of protein phosphatases (TCPTP, PTP1B, PEP (mouse LYP), SHP1, CD45 and PTP-PEST: IC50 = 1.52, 1.59, 7.56, 23.2, 30.1, and 100 µM, respectively). Does not exhibit any toxicity at pharmacological doses when tested in primary human cell lines.
